Este libro es el resultado de m s de veinticinco a os de docencia de los autores en asignaturas relacionadas con el Dise o de M quinas. Representa un compendio de problemas de examen y de aula desarrollados durante este tiempo.Este libro surge por la carencia de problemas con orientaci n profesional relacionados con el Dise o de M quinas. Sin llegar a ser tan complejos como los problemas de la vida real, superan la orientaci n academicista de las colecciones de problemas existentes actualmente.El libro se encuentra estructurado siguiendo el desarrollo t pico de la asignatura. Se inicia con teor as de fallo bajo cargas est ticas, y contin a con fatiga uniaxial bajo cargas exclusivamente alternantes, despu s de a aden las componentes medias y finalmente se abordan problemas de fatiga multiaxial y da o acumulativo por fatiga. Seguidamente se analizan piezas con grietas sometidas a cargas est ticas y a fatiga, mediante la mec nica de la fractura el stica lineal. Posteriormente se analizan casos de contacto puntual y desgaste para finalizar con el c lculo de diferentes elementos de transmisi n. El ltimo cap tulo est dedicado al an lisis de problemas reales, muchos m s complejos donde se combinan diferentes tipos de fallos. Al final del libro, se puede encontrar un formulario, as como el conjunto de tablas y gr ficas necesarias para la resoluci n de los problemas.
